摘要：
A device for spinal surgery that may be used for tightening a locking cap onto at least a portion of a pedicle screw. The device may include a torque-generating body having a proximal end and an opposing distal end and a drive shaft rotatably driven by the torque-generating body. A proximal end of the drive shaft may be operatively engaged to the distal end of the torque-generating body and an opposing distal end of the drive shaft may engage at least a portion of one of the locking cap and the pedicle screw. An anti-torque device is provided that has an elongated and generally hollow member defining a longitudinal axis. The member has a proximal end and an opposing distal end, where the proximal end of the anti-torque device may be fixed from rotating relative to at least a portion of the torque-generating body and the distal end may be fixed from rotating relative to a spine rod or a pedicle screw.
